TWENTY-FIVE COMPOSITIONS OF THE FORM ABC2 were investigated for possible formation of chalcopyritic semiconducting compounds. Three formed single phase structures on direct reaction of participating elements and normal solidification. They were AgInTe2, CuInTe2, and CuFeSe2. AgInTe2 and CuInTe2 formed a continuous series of solid solutions corresponding to Ag sub x Cu sub 1-x InTe2. Evidence for the formation of CuFeTe2 was found but a single phase compound could not be obtained via normal melting techniques.
